unit a JOHN BAUDTNO, GE l'lillnfilifi COMBINED GAP AND AN'IKSIELABEI y n VICE Application filed April 12,

T (all whom it may concern:

lie it known that 1, Join: lliionino, a citizen of the United States, and a resident of llerrin, in the county of Williamson and the titate of Illinois, have invented certain new and useful Inventions in Combined Caps and Antisplash Devices for Gasoline Tanks, of which the following is a specification.

This invention relates to a cap of peculiar construction to be employed in connection with certain devices usually known as gas savers and applied to automobile engines for the purpose of saving the fumes generated in the tank, said fumes being mixed with air and drawn into the cylinders of the engine by suction. The practical use of these devices has been limited as when the tank is carrying a full supply of fuel and the automobile is driven over rough roads or places the gasoline is splashed into the pipe and carried into the cylinder causing fouling and faulty combustion. They have therefore operated only with partial success and then only as the supply of gasoline was largely depleted.

I have found that by applying my cap to one of these devices now in use this objection to it is entirely removed and that it 0perates perfectly at all time and even with a full supply of gasoline in the tank and on ordinary country roads, acting equally as well under these conditions as when used on perfectly smooth roads with only a small supply of gasoline in the tank.

My invention consists of the novel features of construction and combination of parts hereinafter described, pointed out in the claims, and shown in the accompanying drawings, in which 2- Figure 1 is a vertical section showing my invention complete and in position for use.

Figure 2 is a section on the line 2-2 of Fig. 1 looking upwardly.

Figure 3 is a section on the same line looking downwardly.

.Figure l is a section on the line 4-i of Fig. 1.

Figure 5 is a section on the line 55 of Figure 1.

In the drawings A designates a portion of a tank and B the filling vent flange. The usual filler cap is removed and my devices inserted in place of it.

This consists of a cylindrical body 1 having a lower internally threaded flange 2 to ILLINOIS.

engage the flange B. An annular chamber formed within the upper portion of the body 1 and communicates with a pipe l which leads to or forms part of the gas never. in the top of the body portion is an annular groove 5, and bores 6 connect the chamber 3 with said groove. The body 1. is provided with a dome shaped cap 7 which has an annular groove 8 coinciding with the groove 5 when the cap is threaded to the body 1, as shown in Figure 1. Bores 9 connect the groove 8 with the interior chamber 10 formed in the cap. A conical diaphragm 11 having vent openings 12 is carried by the cap, and in inverted position.

packing ring 18 is placed between the cap and the body 1 and has openings 1& therein, through which communication is established between the grooves 5 and 8. The cap has also a rent 15 to the outer air.

Arranged within the body above described and supported by an interior shoulder is an inner cylinder 16, having a hand bar 18 to permit easy removal from the body 1.

Supported in the cylinder is an inverted cone diaphragm 19 covered by a horizontal diaphragm 20, the diaphragm 19 having suitable vents and the diaphragm 20 having slots 20 oifset with respect to the vents of the diaphragm 19. i

The packing ring 13 is of sufficient width to cover the top rim of the cylinder 16. packing disc 21 is held to the bottom of the cylinder 16 by a retaining plate 22, continuous bores 23 being produced through the plate. the disc and the cylinder bottom, the packing disc resting on the annular shoulder l? of the body 1. I

It will be noted that the vents in both the inverted cones are in their tip or central portions while the slots 20 of the horizontal diaphragm are to one side of the center and out of alignment with those of the cones.

The ope ation of the device is as follows:

Suction from the engine through pipe 4: will draw in air through the vent 15 and will also draw vapor fumes from the tank throu/ h the cones 19 and 11 and through the 90 into the chamber 10 where they will in ith the incoming air. This mix- Y will then be drawn downwardly through bores 9, grooves 5 and 8, through the ring openings 14;, and by way of bores 6 to the annular chamber 3, becoming more ill) thoroughly mixed as they descend, and thence to the feed pipe 4. Any gasoline that .niiay splash upwardly through the ports or bores 23 will strike the inverted cone 19 and any small amount that might wash through said cone vents will be stopped by the horizontal diaphragm 20, and if on very rough roads any small amount should pass through the openings 20 creeping of it up the walls ofthe inner cylinder will be checked by the cone 11. Tests with the device show that it is practically impossible for any raw or nnvaporized gasoline to reach the chamber 10 under any ordinary road or operating conditions.

What I claim is1- "i. The combination with a filler cap having an air vent, of a. series of perforated diaphragnis carried by said cap and arfd in difi'erent horizontal planes, and means for conducting fumes passing through said diaphragins to a fuel supply pipe.

2. The combination with a tank having a tiller opening, a filler cap carried thereby, said cap comprising a cover portion removable f om the body portion of the cap, an inner cylindrical portion removable from the body portion, said body portion having air and gas mixing recesses formed therein, perforated diaphragms carried by the cover portion and the inner cylinder, and a fuel supply portion in communication with the recessed portion of the body, said recessed portion also having. communication through said diaphragms with the tank and through said cover portion with the outer atmosphere.

3. The combination with a gasoline tank having a filler opening, a cylindrical body portion secured thereto and in communication with the interior of the tank through said opening, a removable inner cylinder carried by the said body portion, perforated diaphragms carried by said inner cylinder, theperforations of one diaphragm being offset with respect to the other, a cap for said body portion having an air vent, a perforated diaphragm carried by the cap, the body portion having: an annular chamber formed therein said chamber having free communication with the interior of the cap and with the outer air, and aofuel feed pipe in communication with said chamber.

In testimony whereof I afliX mysignat-ure.
